NB-IoT refers to a cellular-based narrowband Internet of Things, which has become an important part of the Internet of Things. NB-IoT is a new technology emerging in the field of Internet of Things in recent years. It has obvious advantages in technology and application. In addition, the application of narrowband Internet of Things (NB-IoT) technology in the field of fire protection can fundamentally enhance the combat capability of fire fighting forces, avoid fire and reduce the loss of life and property of the people. This thesis analyses and introduces an intelligent fire-fighting system based on the new industry standard, and a smoke-fire detection and alarm device based on the Internet of Things (IoT) platform and Nb-IoT technology. It also puts forward corresponding solutions to the problem of smart smoke, such as the value, advantages and future expectations of the solution.

Abstract: Heart rate (HR) measurement is crucial for newborn infant monitoring in the neonatal intensive care unit (NICU). The widely used contact HR measurement methods based on electrocardiography (ECG) and photoplethysmography (PPG) signals can lead to discomfort and possible skin irritation on neonates, which limit its application in NICU scenarios. In this work, we propose a non-contact HR monitoring method simply using a RGB camera. Eulerian video magnification (EVM) is employed to detect the subtle changes of neonatal faces results from blood circulation. The magnified signal is then transformed to the spectral domain to extract HR information. Compared with the widely investigated independent component analysis (ICA)-based HR measurement method using video recordings, the proposed method can achieve the real time HR measurement, which is a significant superiority in NICU neonatal monitoring. To the best of our knowledge, this is the first study to employ EVM algorithm in real time neonatal HR monitoring.
Abstract: Church heating represents a challenging task because multiple goals have to be fulfilled simultaneously, such as the thermal comfort for the occupants and the optimal internal environmental conditions for the preservation of building components and artworks. In addition, current requirements for environmental and economic sustainability impose to make efforts to minimize the amount of energy needed and the consequent environmental/economic impact. In this context, the present work represents the assessment of the energy, environmental and economic impact of different strategies for church heating, including a novel technology based on the exploitation of renewable energies. The analysis was carried out in a real case-study building, represented by the Basilica di S. Maria di Collemaggio (L’Aquila, Italy), a church of worldwide relevance, currently under restoration.
“I think we ought to read only the kind of books that wound or stab us. If the book we’re reading doesn’t wake us up with a blow to the head, what are we reading for? So that it will make us happy, as you write? Good Lord, we would be happy precisely if we had no books, and the kind of books that make us happy are the kind we could write ourselves if we had to. But we need books that affect us like a disaster, that grieve us deeply, like the death of someone we loved more than ourselves, like being banished into forests far from everyone, like a suicide. A book must be the axe for the frozen sea within us. That is my belief.”

Best is water
— Pindar 476 B.C.
The American Water Works Association (AWWA) has an extensive catalog that sets the standard of care for water quality and piping systems running through all communities.
We approach them from the point of view of education communities; some with agriculture, vast hospital systems heavily dependent upon a higher level of water quality and district energy plants. Like most every technology in the United States, water issues enliven political discourse. Essential features of water supply — such as backflow protection, separation, piping systems to playground water fountains, etc. — are subordinated to fury over to access and tariff issues. For the moment we steer away from them.
The landing page for the AWWA standardization enterprise is linked below:
The original University of Michigan standards advocacy enterprise engaged in some back-and-forth with the backflow and cross-connection technical committees. It found ambiguity in the language found in AWWA C510-C511-C512 covering reduced pressure zone (RPZ) values that caused some education facility units to over-specify RPZ valves for all facility classes. Many research universities have enterprises that create toxic water waste which must be blocked from entering the municipal water supply. Some of that back-and-forth is recounted in the workspace linked below.
We found that minimum requirements for backflow prevention technology was easier managed at state level plumbing safety administrative boards.
Several AWWA standards are now open for public review; AWWA G430 Security Practices for Operation and Management among them. We point you toward them; though, in the interest of resource conservation, we will follow but not advocate user-interest in this product at the moment. It appears to have stabilized compared with other standards in the water safety domain (though that could change).
Comments due August 9th.
We find AWWA best practice literature heavily referenced in school district, college and university design guidelines and construction contracts. We do a status check of the AWWA suite every month during our Water teleconferences. See our CALENDAR for the next online meeting; open to everyone.
